Reports in Portugal state his old employers are keen if the Brazil international decides to ask for a move away from the Etihad, having only arrived in the summer from Real Madrid for £25million.
It’s believed the 26-year-old is concerned he could miss out on next summer’s World Cup finals in Russia if he is not playing more regularly for Pep Guardiola, who substituted him at half-time in last Sunday’s late 2-1 home win over West Ham United.
The City chief has consistently picked Kyle Walker ahead of him in his preferred position and he has even been overlooked at left-back, with midfielder Fabian Delph holding down that option in the absence of the long-term injured Benjamin Mendy.
Guardiola promised the two-time Champions League winner he would get plenty of opportunities but Danilo has been limited to just 13 bit-part appearances so far.
The samba star spent three years at Porto before Real came knocking in 2015, with the Portugal giants interested if there is now a loan or a cut-price deal to be had.
